Consider the following equation.

$\displaystyle{\left({32}{{p}}^{{2}}-{3}{{q}}^{{2}}\right)}-{\left({45}{{p}}^{{2}}-{5}{{q}}^{{2}}\right)}+{\left({23}{{p}}^{{2}}-{2}{{q}}^{{2}}\right)}\usepackage{cmbright}\Huge\$ = ________

Fill in the blank with the missing term. To represent the exponent $\displaystyle{{a}}^{{b}}\usepackage{cmbright}\Huge\$ , write a^b.
